High Flow Car Air Filter 4 Inch Inlet 100mm, Cotton Cleanable Element

Upgrade your engine’s breathing with the High Flow Car Air Filter for a 4 inch (100 mm) inlet. This mushroom‑head, bolt‑on air intake filter is designed to sit directly in a 100 mm system, moving the air intake away from the hot engine bay for cooler, oxygen‑rich air that supports stronger throttle response and potential horsepower gains. The washable, reusable filter element reduces ongoing costs and waste while helping your engine perform more efficiently.

Built from rugged cotton gauze and iron mesh, with rubber and stainless steel components, this filter is designed for durability and reliability. The cotton gauze and iron mesh maximize airflow while smoothing airflow to the engine, which helps improve throttle response. The mushroom head design includes a secure C‑clip connection to keep the filter tight and leak‑free, so you can drive with confidence. It’s a practical replacement for aftermarket intake systems, combining easy installation with improved air delivery and performance benefits.

Stop pulling hot air from the engine compartment and enjoy the benefits of a cold air intake—cooler air means denser oxygen for more efficient combustion, potentially stronger power delivery, and better fuel efficiency. The air box design stores a plentiful supply of fresh air, reducing the risk of intake bottlenecks and helping maintain steady airflow even during high-demand driving.
